TRINAMIC Introduces Discrete MOSFET Chips

TRINAMIC, a supplier of stepper motors and motion controls, is a world leader in the industry and has introduced a series of discrete MOSFET integrated circuit chips. This series is a complementary product specially designed for TRINAMIC's popular motor drive and pre-driver chips. The full-bridge/half-bridge MOSFET package is ideal for stepper motors with drive coil current peaks between 2.5A and 5.5A and voltages between 30V and 60V.

TRINAMIC's new MOSFETs product line, coupled with the popular TMC262 stepper motor driver chip, perfectly matches motors with sizes between NEMA 24 and 34, typically delivering 1.1 to 4.4 ft.-lbs. of torque. The MOSFET series and pre-driver chips have been carefully designed to achieve minimal power consumption and heat consumption, providing the designer with the most compact PCB design.

TRINAMIC's founder and CEO Michael Randt said: "TRINAMIC offers a full range of integrated MOSFET stepper motor driver ICs (such as TMC2660, etc.) for peak currents up to 2A or NEMA23 size motors. Customers expect us to provide applications A complete solution for larger size and higher torque motors, so we developed pre-matched discrete MOSFET bridges to meet higher voltage and coil current requirements."

TRINAMIC's discrete MOSFETs use CMOS technology to conduct internal resistance RDS between 40 and 70 milliohms, while typical conduction resistances RDS using BCDMOS integrated MOSFETs are between 200 and 600 milliohms. Therefore, the integrated driver/MOSFET combination is only suitable for relatively low current ranges, while the discrete MOSFET motor driver chip can support higher voltage/current combinations.

Discrete MOSFETs have excellent on-resistance internal resistance (RDS) performance, achieving higher energy efficiency and lower heat loss. By dividing the motor pre-driver and power MOSFET bridge into two discrete devices, engineers have the flexibility to design board layouts to meet space constraints and power consumption requirements. TRINAMIC also provides designers with several proven PCB layouts to reduce board size and heat consumption.

Ye Hong, senior product manager of TRINAMIC authorized distributor Shijian, said: “The new discrete MOSFETs series increase energy efficiency, reduce heat consumption, and simplify the design of PCBs, making TRINAMIC's popular pre-driver chips even more powerful. Provides cost-effective options."
